DST Young Scientist, Project adviser, Research Fellow

Dr. Shankar Pidishety received his Master’s degree from Osmania University, Hyderabad in 2008, and Ph D degree from School of Physics, University of Hyderabad, Telangana, India in 2014. His Ph D work was focused on complex optical fields interaction with surface plasmons under the guidance of Prof. Nirmal K Viswanathan. After that, he worked as a DST Young Scientist (and as a post-doctoral fellow) at Indian Institute of Technology Madras, Chennai, India during 2014-2017. Where, he worked with Prof. Balaji Srinivasan on generation and amplification of complex structured through the optical fiber devices. He also worked as a Research Fellow at Optoelectronics Research Centre, University of Southampton, UK during 2017-2020. Where, he worked on different fiber lasers, amplification of higher order modes, diamond Raman lasers in association with HPFL research group led by Prof. Johan Nilsson. Then he associated as a Research Fellow with ORC Nanophotonics & Metamaterials research group leading by Prof. Nikolay Zheludev, to explore his further research interests. He also worked with Boston University, USA and other Universities as part of collaboration research work. Dr. Pidishety had 2-independent project grants of worth £5million, funded by Department of Science and Technology, India and ORC, University of Southampton towards his research at IITM and in collaboration with University of Southampton during 2015-2017. He also has 3-Patents on fiber coupler device, for his research credit. He was awarded an Young Scientist award by Dr. K V Rao Scientific Society, India for his Ph D research contributions. The Marie-Curie Fellowship (under International Research Staff Exchange Scheme, 2015-2016), JRF/SRF fellowship, Travel grant award and Best poster award are few more recognitions add to his research career. Apart from his research work, he actively involves in scientific events and served as a president to an OSA student chapter, University of Hyderabad during his Ph D research. His inspiring life journey has been featured on a YouTube Channel as well. He has co-authored more than 40 journal and international conference publications.
